Chiral topological phases in optical lattices without synthetic fields
Hoi-Yin Hui, Mengsu Chen, S. Tewari +1
Synthetic fields applied to ultracold quantum gases can realize topological phases that transcend conventional Bose and Fermi-liquid paradigms. Raman laser beams in particular are…
Correlated Spin-Flip Tunneling in a Fermi Lattice Gas
Wenchao Xu, William Morong, Hoi-Yun Hui +2
We report the realization of correlated, density-dependent tunneling for fermionic 40K atoms trapped in an optical lattice. By appropriately tuning the frequency difference between…
Quantum anomalous Hall state from spatially decaying interactions on the decorated honeycomb lattice
Mengsu Chen, Hoi-Yin Hui, Sumanta Tewari +1
Topological phases typically encode topology at the level of the single particle band structure. But a remarkable class of models shows that quantum anomalous Hall effects can be d…
